# First Pass Training of the ViDiCheck Tool

1. With a sufficient small sample size established, you can train the tool to begin the bootstrap method of applying labels. From the Tool Parameters panel, press Training Set.

2. For the initial training pass, use the default settings in the Select Training Set dialog.

3. In Tool Controls, press the Brain icon to begin the training of the tool.

   The time to train the tool is dependent on the size of the image database being trained and the GPU being used.

4. Once the tool has been trained, you can open the Database Overview panel to begin reviewing the results.

   Note: For more information about the results, refer to the Statistical Results, Blue Locate Tool – Statistics and Blue Read Tool – Confusion Matrix (the Blue Locate and Blue Read tool share the same statistical approach, so the information is applicable to both).
